Application February 7, 1935, Serial No. 5,471 Renewed May 5, 1936 2 Claims.

This invention relates to an improvement in cop winding machines and more particularly to an improved drive for actuating the spindle shaft of winding machines in which the winding spindle both rotates and reoiprocates. I

Further in accordance with the present invention an improved drive for actuating the spindle shaft of the winding machine is provided whereby various patterns or forms of winding may be resorted to.

The invention together with its objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawings wherein:

Figure 1 is a side elevational view illustrating the application of the invention.

Figure 2 is a top plan view.

Figure 3 is a fragmentary enlarged sectional View illustrating certain details to be hereinafter more fully referred to.

Figures 4, 5, 6 and '7 are detail views taken substantially on the lines i4, 5-5, 6-45, and 1-1 respectively of Figure 1.

Figure 8 is a perspective view of the slotted end of the spindle shaft.

Figure 9 is a perspective View of a pin hereinafter more fully referred to.

Referring to the drawings by reference numerals it will be seen that the numerals l and 2 indicate generally bearing supports for the spindle shaft 3 between which extends a frame bar 4.

The shaft 3 has a non-threaded end provided with a slot 5 and this end of the shaft is received in a tubular shaft section 6 journaled in the bearing l. Extending transversely through the shaft section 6 is a pin 1 that engages the slot 5 of the spindle shaft 3.

On the outer end of the shaft section 6 is a reduced extension 6' to which is secured as at 'l' a friction disk 8 that is adapted to be moved into and out of engagement with a power wheel, a portion of which is shown in Figure 1 and indicated by the reference numeral 9. For shifting the shaft section 6 axially, there is provided an arm Ill secured to the shaft section 6 and having a bifurcated upper portion straddling the bar 4. For the member ID there is a guide rod l l threadedly engaged with the arm l0 and having a free end operating through an opening I2 provided in the bearing standard I. For shifting the arm Hi, there is provided a rod l3 that is threadedly or otherwise secured to the arm l0 and extends as shown in Figure 1. Interposed between the arm Ill and a shoulder 6a of the shaft section 6 is a suitable bearing l2.

In accordance with the present invention the shaft 3 is provided with, in the present instance, three threaded sections a, b and c and the threads of each section are disposed at a predetermined pitch so that a corresponding number of patterns or forms of winding may be attained, each section of threads resulting in a particular pattern. 10

Cooperable with a selected thread section is a pin I5 that is adapted to be passed through a selected one of the openings It provided in the bar 4, and this pin has a reduced working end lEia adapted to cooperate with the threads of a 15 selected section a, b or c to cause a reciprocatory movement of the shaft 3 incidental to the rotary movement of the shaft in order that a desired winding pattern may be attained. It will thus be'seen that by providing three different thread sections, such as sections a, b and c, a desired one of three different types of thread windings may be attained. In this connection it will be apparent that with the head |5a of the pin l5 engaged with the threads of the selected section the shaft 3 will be caused to reciprocate for the length of that particular thread section during the rotative movement of the shaft. Also, by proper manipulation of the rod l3 the shaft 'section 6 is shifted axially of the shaft 3 to move the friction wheel or disk 8 into and out of engagement with the power wheel 9 to control the transmission of power from said wheel to the spindle shaft of the cop winding apparatus.

Having thus described the invention, what is claimed as new is:

1. In a cop winding machine, a spindle driving shaft, a tubular shaft section bearings for said spindle shaft and said shaft section, a bar con- 'necting said bearings, means connecting said sp-in- 40 dle shaft and said tubular shaft section in driving engagement with one another, driving means associated with said tubular shaft section for rotating the spindle shaft, said spindle shaft being provided with a plurality of sections of va- 45 riously pitched threads, and said bar being provided with a plurality of openings, and a pin adapted to be engaged in a selected one of the openings and having an end engageable with the threads of a selected section for causing reciprocatory movement of the shaft during rotative movement thereof.

2. In a cop winding machine, a spindle shaft, and means for rotating and reciprocating said spindle shaft including a plurality of thread sec- 55 tions on the spindle shaft, each thread section differing from the other thread sections, with the threads of each section pitched to produce a predetermined pattern winding, a fixed member mounted adjacent to and paralleling the thread equipped portion of said shaft, said member being provided with a plurality of openings, and a pin insertable in a selected one of the openings and having its end engaging with the threads of a selected section as for the purpose specified.
